The level of influenza activity in China continues to rise and is at the peak of influenza epidemic

According to the official Weibo news of the National Health and Wellness Committee, the data released by the China Influenza Surveillance Network in the second week of 2019 (January 7, 2019, January 13, 2019) shows that the country is north and south. The level of influenza activity in the provinces continues to rise and is in the peak of influenza epidemics in winter and spring of 2018-2019. The main subtype of influenza virus detected was A(H1N1), followed by A(H3N2) subtype, but very small amounts of B (Victoria) and B (Yamagata) lines were also detected.
At present, the overall activity level of influenza virus in the country is lower than that in the same period of 2018. The pathogen analysis did not find significant variation in antigenicity, gene characteristics and drug resistance of the main epidemic strains, and the virus was sensitive to neuraminidase inhibitors.
In the second week of 2019, influenza-like cases reported by sentinel hospitals in the southern provinces (patients with fever and body temperature ≥38 ?C, with one of cough or sore throat) accounted for 5.5% of the total number of visits (ILI%), higher than before One week level (4.8%), lower than the same period in 2018 (6.0%). The ILI% reported by the sentinel hospitals in the northern provinces was 5.3%, higher than the previous week's level (5.2%) and lower than the same period in 2018 (5.5%).
In the second week of 2019, the influenza virus-positive samples detected by the National Influenza Surveillance Network Laboratory were 37.6% positive, with influenza A accounting for 99.4% and influenza B accounting for 0.6%. The positive rate of influenza detection in the southern provinces was 35.7%, higher than the previous week (28.8%); the positive rate of influenza detection in the northern provinces was 39.3%, higher than the previous week (31.4%).
The main subtype of influenza virus detected was A(H1N1), followed by A(H3N2) subtype, but very small amounts of B (Victoria) and B (Yamagata) lines were also detected. Pathogenic analysis revealed no significant variation in antigenicity, gene characteristics, and drug resistance among the major strains, and the virus was sensitive to neuraminidase inhibitors.
Worldwide, in the temperate regions of the northern hemisphere, the level of influenza activity continues to rise slowly. In South Asia, the number of influenza virus tests has risen sharply in recent weeks, mainly due to the increase in the number of A(H3N2) tests in Iran and the continued detection of the H1N1 virus in India. In the temperate regions of the southern hemisphere, influenza activities have entered the non-popular level, with the exception of parts of Australia. Worldwide, seasonal influenza is dominated by subtype A H1N1.
